Bug#744267: eggdrop: GPL + 4-clause BSD incompatibility

[Vincent Cheng <vcheng@debian.org>]

Source: eggdrop
Version: 1.6.19-1
Severity: serious
Justification: Policy 2.3

Dear Maintainer,

src/compat/inet_aton.c contains code licensed under the 4-clause BSD license,
which includes the "advertising" clause:

 * 3. All advertising materials mentioning features or use of this software
 *    must display the following acknowledgement:
 *      This product includes software developed by the University of
 *      California, Berkeley and its contributors.

This is incompatible with the GPL [1][2], which is what most of eggdrop's
source is licensed under, making this undistributable by Debian as-is.

Regards,
Vincent
